ATTORNEYS Patented Jan. 6, 1931 I PATENT ()FFICE DANIEL J. IINUCANE, OFBROOKLYN, NEW YORK LEADER-PIPE STRAP Application filed September Thisinvention relates to straps or hands adapt-old for use in the attachmentof waterconductor or leader-pipes to the walls of buildings and is inthe nature of an improvement upon the invention disclosed in LettersPatent of the United States Number 1,676,485, granted to me on J uly 10,1928.

Leader-pipes, in accordance with a practice widely followed, aresupported by placing the sides thereof between the arms of a U-shapedstaple or bracket having a central prong adapted to be driven into thewall. A Wire attached to the outer ends of the staple arms and spanningthe front surface of the leader-pipe holds the latterin its position inthe staple. In'order to conceal the staple and wire, a metal band whichembraces the front and sides of the leader-pipeis then i the wall of thebuilding.

ferred to above, disclosure is-made of a band yet adaptable placed overthe fasteningwith end portions of the bands folded outward to lie flatagainst In my patent reof thecharacter indicated and suitable for thispurpose, said band comprising embossed ornamental. ends and successivebody portions having reinforcements embossed therein, the body portionsbeing separated from one another and fromthe ornamentalends by bendingzones adapting the strap to be a bent into conformity with theleader-pipe and with the wall of the building. These features are alsoutilized in the illustrative embodiment of the present invention.

It'is an object of. the present invention to a provide a strap capableof effecting a more complete concealment of the leader-pipe supportingstaple and wire than heretofore, and to installations varying through aconsiderable range.

It is a further object to provide a construction in which the end andbody portions are a more rigid than heretofore and in which the bendsbetween the side body portions and the ends of the strap are adapted tobe more sharply defined so that the body portions and ends maynot mergethrough a curved portionof large radius but be each in its separateplane. Because of these features the strap is adapted to grip the pipemore securely than the prior construction and to 6, 1928. Serial No.304,211.

serve more effectively as a support for the pipe, whether used inconjunction with the staple or other spacer or used separately forgripping the pipe directly against the wall.

Leader-pipes are generally standardized so that a line of supportingstraps suitable for all usual installations may be confined to a smallnumber of standard sizes so far as the requirements imposed by variationin leader-pipe dimensions are concerned.

It is common practice, however, for architects to specify that theleader-pipe be supported at a distance outward from the wall of thebuilding, such installation being in some cases necessitated byirregularities in the face of the building and in other cases considereddesirable for other reasons. Such spacing requirements on different jobsvary considerably. It is, accordingly, an important aim of the presentinvention to provide a strap which is adaptable to all usual spacingrequirements and which therefore can be made in one standard size for agiven size of leader-pipe.

It is a further object of the invention to provide flanges along theedges of the strap in order that a housing or boxing may be formed whenthe strap is bent into conformity with the leader-pipe to completelyconceal the staple and wire. Such flanges are designed to extendcontinuously throughout the length of the strap except at the particularpoints at which bending is desired, and therefore cause the bends to besharply delined and prevent deformation elsewhere than at the lines ofbending.

Other features of the invention relate to the cutting of these flange-sin the bending zones between the side and end portions, and to theoffsetting of adjacent ends of the flange sections between the front andside body portions so that the flanges will be situated in such relationto one another that they will not interfere with the desired bending ofthe strap. I

' Figure 2 is a view similar to Figure 1 showing anv identical strapapplied to another installation in which the spacing requirementsare'different from those of Figure 1 Figure 8 is a fragmentaryverticalsectional view through a leader-pipe and the support-Q ingstrapof Figures land 2 I 4 7 2 Figure 4 is an edge view of a strap of "thekind disclosed in Figure 1 showing .the strap in the form in which it'isreceived on the job;and p F igure. 5 is a plan Viewof the strap shown inFiguren L, I In Figurel aaleader pi peil is: shown snippor'ted from abuilding wall 2 by means a U-shaped bracket 3 'havinga central drivingprong-N4 penetrating the wall. 'TIhe-leaderpipe is bound to thebracketby a wire 5 passed around the front. fac'e 'of the :leaderpipeand wrapped-at its'ends'around hooked ends 6 at the outer ends of arms?of the bracket "3. It will be observed ,that the bracket 3 does not haveits shank 4 driven completely into the Wall but that it is spacedoutward arshort distancefromzthe wall; The leader-pipe itselfmay beregarded, as one of standard size. 2 y

. The bracket, 3 and-wire 5-are concealed and substantially housed by afacing strap 8.

Such strap comprises flangedend portions 9 having ornamental-embossments10 formed therein. Su-chstrap further comprises 'acentralbody portion 11and side body :portions 12 and 1-3 which body'portions have reinforcingembossment-s 14:, 15, and 16, formed in their respective faces. Thecentral body .por

tion 11 is provided with side flanges 17 :and

' the side bodyportions l2-and 13 areprovided with side flanges 18 and19 respectively. These flangesarea'dapted-to form upper and lowerhousing walls and to engage the front and side faces of the leader-pipewhen the strap is bent into conformity with theleaderpipe. Intermediatethecentral body portion 11 and the side body portions -12 and 13. thereinforcing enibossments are omitted-so'that flexible bending z'onesareprovided to facil-i: tate application of the-strap to the leaderpipe. Atthe bending'zone 20-the flanges 17 are separated from the flanges 18 andat the bending zone 21 the flanges 1-7 are separated from-the flanges19. Inbrderth-at'the flanges shall not interfere with "bending of thestrap the inner ends of fiange s-1'8' and :19 are'formedrwith offsets-22and 23 to disalign them with respect'tothe flangesili'. x

It will be seen from a comparisonof 'Figures 1 and 2thatineifectingdifferentinstallati'ons, it will be. necessaryto bendoutward the ornamental end :lportions of the strap at different points.In order to-enable this to be done, orovision is. made "between thebodyportion 12 and one end portion 9 of an unembossed bending portion 21 and between body portion 13 and the opposite end portion 9 of anunembossed bending, portion 25. These bending portions 24 and 25 aremade of substantial length suflicient to accommodatejall' of thevariations ordinarily encountered in the spacingof leader-pipes outwardfrom walls. As seen in Figure 1, for

example the leader pipe is located fairly close to the "wall and thestrap is bent in portions ofthe bending zones 24 and 25 closely adjacentto the body portions 12 and 13. In Fig ure 2 on the otherhand, theleader-pipe is spaced a substantial distance outward from therwall-andthe bending ispeflectcd in the bending zones 24,.and 25, atpoints'fclosely adjacent to the ornamental end portions9.

In order to effect this bending, the workman determines by measurementthe locations inthe bending zones at which the bending is required bythe particular. leader-pipein- 'stallation onwhich he is working andthen cuts through the flanges 18 and 19 in the appropriate portions 0fthe bending zone for permitting the bends to be formed at-the de siredpoints. The strap is then bent into the shape shown in Figure 1 or 2 andis either soldered to the leader-pipe or secured in place by nails 26driven into the wall ofthe building. If desirecLit may be bothsoldered'to the leader-pipe and nailed to the wall, to assist in supporting theleader pipe in place.

It will be-seen that thezflanges 18 and 19 should preferably be cutinorder to permit bending in thebending. zones 24 and 25 and that whenso 'cutT'the bending is confined :in

each zone to 'a :line joining the cuts. 'The bends will, therefore,be:sharply defined so that theproduotion of :a neat, attractive,

workmanlike job will result asa'mat'ter of 2 course.

' WVhile I have illustrated and described in detail certain preferredforms of my invention, it is to beunderstood-lthat changes may be madetherein andthe invention embodied in other structures. I do not,therefore, desire to limit :myself to the specific constructionsillustrated, but intend to cover my invention broadly in whatever formits principle may be utilized.
